在 Windows 7 上安装 Haskell 模块
昨天我尝试通过 cabal 安装 Haskell 模块，以便熟悉 Haskell 中模块的安装。我必须先安装 cabal。
我的系统：Windows 7
Haskell-编译器版本：GHC 7.0.2（链接http://www.haskell.org /ghc/download）
阴谋集团：http://haskell.org/cabal/download.html< /a>
我将一步步描述这个过程，希望您能指出我在 cabal 和 cabal 软件包安装过程中的错误行为。
过程：
安装Haskell编译器GHC 7.0.2
从 Windows 7 开始菜单启动 GHCi，在 DOS 窗口中给出以下输出：
GHCi，版本 7.0.2：网站：？寻求帮助。 正在加载包 ghc-prim ...链接...完成。 正在加载包integer-gmp ...链接...完成。 正在加载包基础...链接...完成。 正在加载包 ffi-1.0 ...链接...完成。 前奏>到目前为止一切顺利：基础包中的每个功能都可以访问并且按照其应有的方式运行。
结论：GHCi 安装不包含错误步骤。
从源代码下载
cabal.exe（参见简介），将其复制到C:\ghc\ghc-7.0.2\bin（添加到%Path%-variables中）- 下载
cabal -install-0.8.2.tar.gz因为该网站建议用户全新安装需要该软件包。 - 打开新的 dos 提示符窗口
- 键入
cabal update（根据站点的建议），它确实更新了列表并返回到用户提示模式 - 键入
cd C:\pathwhere\cabal-install-0.8.2 .tar.gz（切换到 cabal-install 文件所在的目录） 输入
cabal install cabal-install-0.8.2，此后安装开始创建以下输出在dos框中：正在解决依赖关系... 正在下载容器-0.3.0.0... 配置容器-0.3.0.0... 预处理库容器-0.3.0.0... 构建容器-0.3.0.0...

正如人们所看到的，输出表明了一些错误，但我不知道它们的含义。我继续尝试安装我的代数包，重点是使其可用于步骤 1 中的 Dos-Interpeter。
再次在 dos-box 输入提示中，我输入
cabal install constructive-algebra，这创建了这个输出：正在解决依赖关系... cabal：无法配置 algebra-0.0.0.1。它要求基数>=3.0 && <4.1 对于base的依赖度>=3.0&& <4.1 有这些包： base-3.0.3.1、base-3.0.3.2 和 base-4.0.0.0。然而，它们都不可用。 由于顶级依赖项 base -any，base-3.0.3.1 被排除 由于顶级依赖项 base -any，base-3.0.3.2 被排除 由于顶级依赖项 base -any，base-4.0.0.0 被排除
我认为该软件包尚未安装。我需要有人可以解释我需要执行哪些具体步骤才能使模块正常工作。
感谢您阅读这篇文章并以让我理解它以及解释器和编译器工作的方式回答。
Yesterday I tried to install a Haskell-module via cabal, in order to get aquainted with the installation of modules in Haskell. I had to install cabal first.
My System: Windows 7
Haskell-Compiler Version: GHC 7.0.2 (Link http://www.haskell.org/ghc/download)
Cabal: http://haskell.org/cabal/download.html
I will describe the process step by step, hoping that you may specify my wrong doings during both cabal and the package installation with cabal.
The procedure:
Installed Haskell Compiler GHC 7.0.2
Starting GHCi it from the Windows 7 start menu, gives following output in a DOS-window:
GHCi, version 7.0.2: Website :? for help . Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. Loading package ffi-1.0 ... linking ... done. Prelude>So far so good: Every function inside the base packages is accessible and functions just the way its supposed to.
Conclusion: The GHCi installation contains no erroneous steps.
Downloaded
cabal.exefrom source (see introduction), copied it into C:\ghc\ghc-7.0.2\bin (which is added into %Path%-variables)- Downloaded
cabal-install-0.8.2.tar.gzas the site advises users that the packeage is needed for a clean install. - Opened new dos prompt window
- Typed
cabal update(as advised by site), it did update the list and returned to user prompt mode - Typed
cd C:\pathwhere\cabal-install-0.8.2.tar.gz(switched into the directory where the cabal-install file is located) Typed
cabal install cabal-install-0.8.2, thereafter the installation started creating following output in the dos-box:Resolving dependencies... Downloading containers-0.3.0.0...

The exception was: ExitFailure 1My Conclusion:
As one can easily see, the output indicates some errors, but I got no idea what they mean. I continued trying to install my algebra package focusing on making it availible to the Dos-Interpeter from step 1.
Again in dos-box input prompt, I typed
cabal install constructive-algebra, that created this output:Resolving dependencies... cabal: cannot configure algebra-0.0.0.1. It requires base >=3.0 && <4.1 For the dependency on base >=3.0 && <4.1 there are these packages: base-3.0.3.1, base-3.0.3.2 and base-4.0.0.0. However none of them are available. base-3.0.3.1 was excluded because of the top level dependency base -any base-3.0.3.2 was excluded because of the top level dependency base -any base-4.0.0.0 was excluded because of the top level dependency base -any
I suppose that the package is not installed. I need someone who can explain, what exact steps I need to do in order to get modules working.
Thanks for reading this post and answering in way that makes me understand it AND the Interpreter and Compiler working.

最简单的方法是获得像 DasBoot 推荐的 Haskell 平台，但无论如何我都会尝试回答您的问题：
1）对于您问题的第一部分，您的安装失败，因为您的路径有问题。找不到工具“ar”。创建库时使用 ar。如果您在命令窗口中仅输入“ar”，它应该返回类似的内容
如果没有，则需要将包含 ar 的文件夹（可能是 C:\ghc\ghc-7.0.2\mingw\bin）添加到 Windows 中的路径环境变量中。
2) 您的代数库不会在 7.0.2 下安装，至少不会开箱即用。代数的依赖项列为“依赖项：base >=3.0 && <4.1”，
但 ghc 7.0 附带了 base 4.3。这就是为什么您收到：
。幸运的是，对于这个特定的软件包，这个问题可以很容易地修复。就做
，这样就可以了
The easiest way is to get the Haskell Platform like DasBoot recommended, but I'll try and answer your questions anyway:
1) For the first part of your question, your installs are failing because something's wrong with your path. the tool "ar" couldn't be found. ar is used when creating libraries. If you type just "ar" in a command window it should return something like
If it doesn't then you need to add the folder containing ar (probably C:\ghc\ghc-7.0.2\mingw\bin) to your path env variable in windows.
2) Your algebra library won't install under 7.0.2, atleast not out of the box. Algebra has a dependency listed as "Dependencies: base >=3.0 && <4.1"
but ghc 7.0 comes with base 4.3. Which is why you received:
Luckily, this can easily be fixed for this particulair package. just do
and that should do it
我从 下载 Haskell 安装了完整的软件包
该软件包包括 cabal。我是win7下运行的，目前没遇到什么问题。
FWIW，如果您单击帖子中的下载链接，然后尝试下载最新版本，则会出现一条大消息，建议从我提供的链接下载 haskell 平台。
I installed the full package from Download Haskell
This package includes cabal. I'm running it on win7, and haven't had any problems so far.
And FWIW, if you click on the download link in your post and then try to download the latest version there is a big message which suggests downloading the haskell platform from the link I gave.
包名称是constructive-algebra，但是它的模块名称是什么？该模块名称是您应该在 ghci 中使用的名称。
the package name is constructive-algebra but what is it's module name? That module name is what you should use in ghci.
